Surf Bait

8 posts in this topic

I want to build a surf bait I can cast with a surf rod against the wind. The ideal weight would be 2.5 Oz., but I know I can't achieve that and still maintain a topwater lure similar to a Zara Spook in size. In any case, what should I build the lure body with if I want to keep the length at no more than 5 inches, yet achieve the greatest weight without sinking to the bottom? Once I'm in the ballpark I can play with additional weights to make some topwater and some suspending lures. I have a metal working lathe for turning wood and metal.

2.5ozs is 70gm. With 10% buoyancy, this means a body volume of 77gm/cm3 is required for a casting weight of 70gm.

I experimented with a computer model I have. Probably not the right shape, but will give you an idea of requirements. I have just cut a simple fillet rad around the edges, not pretty, but if you cut more fancy curves, you will be reducing the volume further.

This picture shows a body of dimensions:

length 125mm, depth 40mm, thickness 20mm. Its casting weight is 44g or just over 1.5ozs.

To achieve 2.5ozs casting weight, the required body dimensions are:

length 125, depth 49mm, thickness 25mm.

This is a picture of the larger profile after shaping. The casting weight reduces to 60gm or 2.1ozs.

Those are awesome designe Vodkaman! What material do you use for the body? By the way, the computer graphics are stunning. What program are you using?

It is a CAD program called CATIA V5. It is the first time I have modelled a body to completion. I am very pleased with the result. This one was drawn just for an exercise, I normally only use the program for lip and body profiles.
